Hello,

Here are the torque stats for the upper and lower intake manifold.

Lower intake manifold (intake manifold to cylinder heads)

Final torque: 25 Nm (18 ft-lb)
Best practice is a staged approach:

Stage 1: snug/initial pass (light torque)
Stage 2: 18 ft-lb (25 Nm) final, following the factory-style center-out sequence

Upper intake (plenum) to lower intake

Torque: 89 in-lb (7.4 ft-lb / 10 Nm)
(That’s the common spec for the plenum-to-manifold bolts on the 4.6 modular family.)

Please use 2CarPros anytime we are here to help. Ken
